Checking settings
The current Collision Warning settings can be checked by going into the menu system at
168 04 Comfort and driving pleasure
Collision Warning with Auto-brake (option)
Car settings Collision warning settings. See page 122 for more information on the menu system.
Limitations
Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if the driver is not looking straight ahead
may make the visual warning signal in the windshield difficult to see. For this reason, always activate the audible
warning signal in such conditions.
NOTE
The visual warning signal may be temporarily disengaged in the event of high passenger compartment temperature
due to strong sunlight, etc. If this occurs, the audible warning signal will be used, even if it has been deactivated in
the menu system.
Warnings may not appear if the distance to the vehicle ahead is very small or if steering wheel and pedal movements
are great, for example, due to a very active driving style.
WARNING
In certain situations, the system cannot provide warnings or warning may be delayed if traffic conditions or other
external factors make it impossible for the radar sensor or camera to detect the vehicle ahead.
Warnings may not be provided if the distance to the vehicle ahead is short, or if movements of the steering
wheel/brake pedal are great, such as during active driving.
The sensor system has a limited range for stationary or slow-moving vehicles and may therefore give delayed or
no warnings if your vehicle's speed is above approximately 45 mph (70 km/h).
Warnings for stationary or slow-moving vehicles may not be provided in dark conditions.
The Collision Warning system uses the same radar sensors as Adaptive Cruise Control. For more information on the
radar sensor and its limitations, see page 160
.
If no warning is given, or if a warning is delayed, Auto-brake will also not be provided or will be delayed.
NOTE
If warnings are given too frequently, the warning distance can be reduced (see "Setting a warning distance" on page
167). This causes the system to provide later warnings, which decreases the total number of warnings provided.
The camera's limitations
The camera is used by Collision Warning with Auto-brake, Driver Alert Control (see page 171
), and Lane Departure
Warning (see page 174
).
NOTE
Keep the section of the windshield in front of the camera clean and free of ice, snow, or condensation.

This function is intended to alert the driver if his/her driving becomes erratic, such as if the driver is distracted or
fatigued.
A camera monitors the painted lines marking the lane in which the vehicle is traveling and compares the direction of
the road with the driver's movements of the steering wheel. The driver is alerted if the vehicle does not follow the lane
smoothly.
NOTE
The camera has certain limitations, see page 168
.
DAC is designed to help detect a slowly changing driving pattern. It is primarily intended to be used on main roads
and is not meant for use in city traffic.
WARNING
DAC is not intended to extend the duration of driving. Always plan breaks at regular intervals to help remain
alert.
In certain cases, fatigue may not affect the driver's behavior. In situations of this type, no warning will be
provided. Therefore, it is important to take breaks at regular intervals, regardless of whether or not DAC has given a
warning
Limitations
In certain situations, DAC may provide warnings even if the driver's driving pattern has not become erratic.

Introduction
The park assist system is designed to assist you when driving into parking spaces, garages, etc.

At highway driving speeds, fuel consumption will be lower with the air conditioning on and the windows closed
than with the air conditioning off and the windows open.
Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.
Other factors that decrease gas mileage are:
Dirty air cleaner
Dirty engine oil and clogged oil filter
Dragging brakes
Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard maintenance intervals.
WARNING
Driving with the trunk open : Driving with the trunk open could lead to poisonous exhaust gases entering the
passenger compartment. If the trunk must be kept open for any reason, proceed as follows:
Close the windows
Set the ventilation system control to air flow to floor, windshield and side windows and the blower control to its
highest setting.
Weight distribution affects handling
At the specified curb weight your vehicle has a tendency to understeer, which means that the steering wheel has to be
turned more than might seem appropriate for the curvature of a bend. This ensures good stability and reduces the risk
of rear wheel skid. Remember that these properties can alter with the vehicle load. The heavier the load in the cargo
area, the less the tendency to understeer.
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle handling. Therefore, check that the tires are inflated to
the recommended pressure according to the vehicle load. See the "Tire pressure" section. Loads should be distributed
so that capacity weight

or maximum permissible axle loads are not exceeded.
Driving through water
The vehicle can be driven through water up to a depth of approximately 9 in. (25 cm), at a maximum speed of 6 mph
(10 km/h).
Take particular care when driving through flowing water.
Clean the electrical connections for trailer wiring after driving in mud or water.
When driving through water, maintain low speed and do not stop in the water.
WARNING
After driving through water, press lightly on the brake pedal to ensure that the brakes are functioning normally.
Water or mud can make the brake linings slippery, resulting in delayed braking effect.

Examine tires carefully (the spare tire as well), and replace those that are worn. Check tire pressures.
The brakes, front wheel alignment, and steering gear should be checked by a trained and qualified Volvo service
technician only.
Check all lights, including high beams.
Reflective warning triangles are legally required in some states/provinces.
Have a word with a trained and qualified Volvo service technician if you intend to drive in countries where it may
be difficult to obtain the correct fuel.
Consider your destination. If you will be driving through an area where snow or ice are likely to occur, consider
snow tires.
Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, the following advice is worth noting:
Make sure that the engine coolant contains 50 percent antifreeze. Any other mixture will reduce freeze protection.
This gives protection against freezing down to - 31°F (-35°C). The use of "recycled" antifreeze is not approved by
Volvo. Different types of antifreeze must not be mixed.
Volvo recommends using only genuine Volvo antifreeze in your vehicle's radiator.
Try to keep the fuel tank well filled - this helps prevent the formation of condensation in the tank. In addition, in
extremely cold weather conditions it is worthwhile to add fuel line de -icer before refueling.
The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-weather starting as
well as decreasing fuel consumption while the engine is warming up. For winter use, 5W -30 oil, particularly the
synthetic type, is recommended. Be sure to use good quality oil but do not use cold-weather oil for hard driving or in
warm weather. See page 272
for more information on engine oil.
NOTE
Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at
additional charge.
The load placed on the battery is greater during the winter since the windshield wipers, lighting, etc. are used more
often. Moreover, the capacity of the battery decreases as the temperature drops. In very cold weather, a poorly charged
battery can freeze and be damaged. It is therefore advisable to check the state of charge more frequently and spray an
anti-rust oil on the battery posts.
Volvo recommends the use of snow tires on all four wheels for winter driving. See the information on page 250.
To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze. This is important
since dirt is often splashed on the windshield during winter driving, requiring the frequent use of the washers and
wipers. Volvo Washer Solvent should be diluted as follows: Down to 14° F (-10° C): 1 part washer solvent and 4 parts
water Down to 5° F (-15° C):
191 05 During your trip
Driving recommendations
1 part washer solvent and 3 parts water Down to 0° F (-18° C): 1 part washer solvent and 2 parts water Down to -18°
F (-28° C): 1 part washer solvent and 1 part water.
Use Volvo Teflon Lock Spray in the locks.
Avoid using de -icing sprays as they can cause damage to the locks.

Emergency towing
Towing eyelet
The towing eyelet is located under the floor of the trunk, with the spare tire. This eyelet must be screwed into the
positions provided on the right sides of either the front or rear bumper (see illustration).
NOTE
On certain models equipped with a trailer hitch, the towing eyelet cannot be screwed into the hole in the rear
bumper. The towing rope should be attached to the trailer hitch instead. For this reason, the detachable section of the
trailer hitch should be safely stowed in the vehicle at all times.
Attaching the towing eyelet
1. Use a coin to pry open the lower edge of the cover.
2. Screw the towing eyelet in place, first by hand and then using the tire iron until it is securely in place.
After the vehicle has been towed, the eyelet should be removed and returned to its storage location.
Press the cover for the attachment point back into position.
Precautions when the vehicle is in tow
The steering wheel must be unlocked. The remote key must be in the ignition slot1.
Attach jumper cables (see page 109) to provide current for releasing the optional electric parking brake and to move
the gear selector from the P position.
The gear selector must be in position N .
Maximum speed: 50 mph (80 km/h). Do not exceed the maximum allowable towing speed.
Maximum distance with front wheels on ground: 50 miles (80 km).
While the vehicle is being towed, try to keep the tow rope taut at all times.
The vehicle should only be towed in the forward direction.

Do not touch any part of the distributor ignition system while the engine is running. This may result in unintended
movements and body injury.
212 06 Maintenance and specifications
Engine oil
Checking the engine oil
The oil level should be checked every time the vehicle is refueled. This is especially important during the period up to
the first scheduled maintenance service.
See page 272 for oil specifications.
Refer to the Warranty and Service Records Information booklet for information on the oil change intervals.
Volvo recommends Castrol.
CAUTION
Not checking the oil level regularly can result in serious engine damage if the oil level becomes too low.
Oil that is lower than the specified quality can damage the engine.

Checking the level
The fluid reservoir is concealed under the round cover at the rear of the engine compartment. The round cover must be
removed first before the reservoir cap can be accessed.
The brake fluid should always be between the MIN and MAX marks on the inside of the reservoir. Check, without
removing the cap, that there is sufficient fluid in the reservoir.
Fluid type: DOT 4+ boiling point >536°F (280°C), P/N 9437433
Replace: The fluid should be replaced according to the intervals specified in the Warranty and Service Records
Information booklet.
When driving under extremely hard conditions (mountain driving, etc), it may be necessary to replace the fluid more
often. Consult a trained and qualified Volvo service technician.
Always entrust brake fluid changing to a trained and qualified Volvo service technician.
WARNING
If the fluid level is below the MIN mark in the reservoir or if a brake-related message is shown in the information
display: DO NOT DRIVE. Have the car towed to a trained and qualified Volvo service technician and have the brake
system inspected.
Filling
Turn and open the cover.
Unscrew the reservoir cap and fill the fluid. The level must be between the MIN and MAX marks.
Power steering fluid
Check the level frequently. The fluid does not require changing. The fluid level must be between the MIN and MAX
